SoniControl @ BMWFW Tag der offenen Tür

The project SoniControl will be presented at the “Tag der offenen Tür” of the Federal Ministry of Science, Research, and Economy on the Austrian National Holiday (26.10.2017). The project will be shown from 10am to 4pm! We hope to see you there to show you a demo of our prototype!

Meet SoniControl @ ARS Electronica 2017

The SoniControl Project will be presented at this year’s ARS Electronica festival from September 7 – 10. See our live demo of how ultrasonic communication works and how we detect and mask it! You can find us in Postcity Linz, first floor, Room No. 11. We are looking forward to see you there!

234 Apps use ultrasonic tracking

A recent study of TU Brunswick (Germany) reveals that many more Apps than expected use ultrasonic information exchange. More: here. The study can be found here. The SoniControl Project Team members currently work on real-time audio processing methods that enable a robust detection of ultrasonic information.

Listen to ultrasonic communication!

We have compiled a set of ultrasonic audio recordings of different mobile apps including Google Nearby-based apps. Since ultrasonic sound is inaudible we have made the sounds visible (by computing spectrograms) and audible (by shifting their pitch to the audible range). The entire dataset can be downloaded under “Ressources” on the SoniControl webpage.
